Java synchronized block vs. Collections.synchronizedMap

Question

Is the following code set up to correctly synchronize the calls on synchronizedMap?

public class MyClass {
  private static Map

        

Answer 1

Collections.synchronizedMap() guarantees that each atomic operation you want to run on the map will be synchronized.

Running two (or more) operations on the map however, must be synchronized in a block. So yes - you are synchronizing correctly.
